Plants that turn their faces to the light. This is the roll call for the open, sun-struck parts of the garden, the borders and banks that bake from morning to evening, where the toughest, brightest, most floriferous plants do their best work.
Clematis armandii is the evergreen clematis, a bold, glossy-leaved vine that breaks nearly every rule of the genus. Where most clematis drop their leaves and climb daintily, this one holds large, leathery, dark green trifoliate leaves the year round and grows with real vigor, then smothers itself in fragrant white flowers at the very start of spring. Few vines open so much bloom so early, and fewer still carry evergreen foliage handsome enough to grow for the leaves alone.
Clematis crispa, the swamp leather flower, is a small and delicate native vine that trades the flat, showy face of a garden clematis for something quieter and stranger. The flowers hang solitary and nodding, little urns of thick, leathery blue-purple, paler within, their four recurved sepals frilled and crimped at the tips like curled ribbon. Slightly fragrant and endlessly charming, this is a clematis scaled for a small garden rather than a barn wall.
Clerodendrum indicum, the Turk's turban, is a bold, tropical-looking perennial that stages two very different shows in a single season. First come tall, nearly unbranched stems, ringed with long narrow leaves and topped in summer by great airy sprays of long-tubed white flowers, shooting outward like a burst of fireworks, which earns the plant its other names, tube flower and skyrocket. Then, as the blooms fade, the real surprise arrives.
Summersweet, Clethra alnifolia, is one of the great fragrant natives of the eastern United States, a shrub of moist woods and pond edges whose white summer spikes carry a honey-and-clove perfume across the whole garden. Colonists called the plant Sweet Pepperbush, for the peppercorn-like seed heads that follow, and Summersweet, for the scent; the flowers even lather softly in water and once served as a field soap.
Summersweet, or sweet pepperbush, is one of the most useful of the native shrubs for moist, shaded ground, and 'Hummingbird' is the compact, free-flowering selection that made the species a garden staple. Like the straight Clethra alnifolia, this is a stoloniferous deciduous shrub that forms colonies in moist, acid soil, valued above all for the upright spikes of intensely fragrant white flowers that perfume the whole garden in the heat of summer, when little else is blooming.
The Japanese clethra is grown for bark as much as bloom. Clethra barbinervis is a tall, tree-like deciduous shrub or small tree from the mountains of Japan and Korea, carrying somewhat fragrant terminal racemes of white flowers in summer, in the same sweet-scented family as the native summersweets. But the real distinction is the bark: smooth and polished, gray to warm brown, and exfoliating in age to a handsome patchwork that makes this one of the finest small trees for the winter garden.
Most of the summersweets drop their leaves and sleep through winter; Clethra pringlei keeps them. This Mexican member of the clan is a broad-leaved evergreen, a large, slow-growing shrub or small tree from the mountain woodlands of northeastern Mexico, and one of the more surprising plants in the genus for a gardener who knows only the deciduous American kinds.
The summersweets are among the most fragrant of American shrubs, and the southern woolly summersweet, Clethra tomentosa, carries the whole tribe's gifts: colonies of upright stems in moist, acid ground, and terminal spikes of white flowers that pour a honey-and-clove perfume across the July garden. Country people knew the plant as Sweet Pepperbush, for the peppercorn seed heads, and the crushed flowers even raise a soft lather once used as a woodland soap.
Cleyera japonica belongs to the tea family, the Theaceae, alongside camellia and tea themselves, and shares the family's glossy, leathery, deep green leaves. In the plant's native Japan the species carries a sacred weight few garden shrubs can claim: this is the sakaki, written with a character that fuses the signs for tree and for god, and the branches are cut for tamagushi, the leafy wands offered at Shinto shrines for blessing and purification. Small, sweetly scented cream flowers open in early summer, followed by berries that ripen from red to black.
Cliftonia monophylla 'Berry Pink' is a rare, pink-flowered selection of the Black Titi, a native evergreen shrub or small tree of the southeastern coastal plain that normally blooms in white. The species haunts the acid bogs, pond margins, and titi swamps from the Carolinas to the Gulf, where the early flowers make the buckwheat tree one of the first and most important nectar sources of the southern year, the source of the prized titi honey.
Clinopodium coccineum is a small, aromatic, semi-evergreen subshrub of the mint family, native to the deep, well-drained sands of the southeastern coastal plain, from Mississippi and Georgia down into Florida. The loose, open frame and small, spicy-scented leaves would earn a quiet place on their own, but the flowers are the event: showy scarlet tubes carried over a long summer season, held out like little trumpets that hummingbirds cannot resist.
'Amber Blush' is a soft-toned selection of the native scarlet calamint, Clinopodium coccineum, an aromatic, semi-evergreen subshrub of the mint family from the deep sands of the southeastern coastal plain. Where the wild species flowers in hot scarlet, this apricot clone brings a gentler, more complicated color to the same tough, hummingbird-loved plant.
Colquhounia coccinea is a showy, soft-wooded shrub of the mint family, clothed in medium-sized leaves that are downy and pleasantly rough to the touch. Through late summer and fall come dense terminal spikes of orange-scarlet, yellow-throated flowers, a hot late-season color that hummingbirds and pollinating insects work eagerly. Plant in a sunny, well-drained site with good soil, where the arching stems can be trained against a warm wall.
The conradinas are dense, aromatic, low shrubs of the mint family, dressed in small, usually needle-like green or gray leaves and hung with little pale purple flowers. Six or seven species grow wild in the southern United States, most of them in Florida on sand or very sandy soil, and all but this one (and one possibly new species) are federally listed as threatened or endangered. Conradina canescens is the common, widespread member of the clan, a somewhat variable plant of the Gulf Coast dunes of northwest Florida and adjacent Alabama.
Some years ago we introduced two selections of Conradina collected on the Styx River in southern Alabama, called 'Low Gray' and 'Low Green', and we hope those clones survive in cultivation somewhere still. On a return visit to the Styx River site we gathered several more cuttings from distinctly low-growing plants. This conradina haunts a sandy woodland and cutover near the Styx River, and may well represent a new, as yet undescribed species; what appears to be the same plant turns up some miles east on Blackwater State Forest in northwest Florida. The Styx River plant differs clearly from the taller, more upright Conradina canescens of the open Gulf Coast.
A small shrub of the Cumberland Plateau, found only on the flood-scoured cobble and sand bars of three river systems in eastern Tennessee and a sliver of Kentucky: the Big South Fork of the Cumberland, the Caney Fork, and the Obed. The rest of the Conradina clan keeps to the sand scrub of Florida and the Gulf Coast of Alabama, sun-baked and semitropical. This species took a different path, north into the cooler uplands, and the cold-hardiness that came with the move is the gift to gardens farther north.
Few native shrubs carry as much quiet history as Croton alabamensis, the Alabama croton, a rarity known in the wild from only a handful of counties along the Cahaba and Black Warrior rivers, where the shrub clings to dry, limestone bluffs. This is a plant of the Southern woodland edge, once more widespread and now treasured wherever a gardener can offer the Alabama croton a home.
Titi is one of the quiet workhorses of the southern wetland, an evergreen to semi-evergreen shrub or small tree that ranges farther than almost any other native of the region, from the coastal plain of southern Virginia down through Florida and west to eastern Texas. In the wild the plant haunts the edges of swamps, bays, and blackwater streams, standing in the wet, acid ground where few woody plants thrive, yet takes with surprising ease to ordinary garden soil.
'Graniteville' is a low, ground-hugging selection of Cyrilla racemiflora, the native Titi, and one of the more distinctive forms of a plant already known for variability. Where the species can build into a small tree, this Woodlanders introduction stays wide and knee-high, and the story behind the plant is a piece of local botanizing: we propagated 'Graniteville' from an almost prostrate individual found years ago on an eroded sandhills seepage slope near Graniteville, South Carolina, and the ground-hugging habit has held true ever since in cultivation.
Winter Daphne is one of the most beloved and most exasperating shrubs in the southern garden, grown for a fragrance that arrives in the dead of winter and carries clear across a yard. In late winter the dense, rounded evergreen opens tight clusters of small, waxy, rose-pink flowers, and the scent, sweet and far-reaching, is the whole argument for growing the plant. This is the non-variegated form, with clear pink bloom and glossy, unmarked deep green leaves.
